I found the Seal Bolt System pretty helpfull. It closed the opening and keeps paint out of your marker. This helps in keeping you from taking your marker apart to clean. The only thing that was difficult is that if you over tighten the screws it won't work. (It took me a while to figure out why it wasn't working) It is a little difficult with a stock on but works none the less.

Conclusion:

I really liked it. It helped out a lot but instally was a bit difficult

Protects the inside of your marker and reduces noise slightly. A cheap upgrade.

Weaknesses:

None.

Review:

I remember the day I went out after buying the Rocket Cock (as it's referred to by some) and played with a few friends of mine. Well, through the course of the day my marker took a close hit to where my Rocket Cock was protecting the cock slot. Paint spattered all over the Rocket Cock, but the insides of my gun were safe. It saved the rest of my day. Instead of spending the next half hour meticulously cleaning out the insides of my marker, I just got ready for the next game. For 15-20 dollars, this upgrade is something you simply CANNOT live without.

Also, you don't have to worry about your marker's cocking bolt catching against anything while it's firing, the Rocket Cock gives your Custom no moving parts on the outside. It's constructed of high impact plastic and you should have no worries about it crapping out on you.

Conclusion:

Buy it because it's cheap, durable, and covers that one chink in the 98 Custom's armor, the cock slot.

98 custom with adjustable stock and a one point harness with a rocket cock and a raised lapco sight.

Strengths:

It quets the gun down a bit and it keeps the crap out.

Weaknesses:

If you have an adjustable stock you cant close it all of the time.

Review:

This is a good buy if you play in harsh conditions but if you play speedball you dont need this too to much. i play in sandy conditions and pretty much all of the crap stays out of the gun, and it makes you feel alot safer when you slide.

This is a good product. It keeps the inside of the marker free from dirt and charging handle does not move forward and back when the marker is fired. Use wire cutters on the flatline shroud to cut a groove for the top over the screw. When you look at it you will know what i'm saying.

Conclusion:

A good war to keep the inside of the marker clean, 15 min install, 30 if you got a flatline. Great for $20
